Of course, laser-guided missiles miss their mark too, but a failed shot from a gun should carry a lot less of a risk than that of a missile. Sadly, if the bullet is ever deployed in combat (and not a test range), it won't carry that eery trail—that's just an onboard LED to prove the thing's agility. Which is a shame! What's more terrifying than a bullet that flies itself? A glowing bullet.
